Ukraine has carried out a strike on Russian military and oil infrastructure in the Caspian Sea, hitting a Russian patrol ship and a Lukoil-operated oil platform, according to the General Staff of the Armed Forces of Ukraine.

The attack, said to have occurred on 19 December, involved several Ukrainian drones targeting a Project 22460 Okhotnik-class patrol vessel patrolling near the Filanovsky oil and gas field.

Ukrainian officials stated that the vessel was struck multiple times, although the extent of damage and its hull number were still being assessed.

Analysts from the open-source intelligence project Kiberboroshno suggested that the ship hit may have been the Rasul Gamzatov.

Additionally, a drilling platform at the Filanovsky oil and gas field, operated by Lukoil, was also reportedly struck by Ukrainian special forces.

The platform, which produces oil and gas, is understood to support Russian armed forces operations. Ukrainian authorities consider Russian oil infrastructure a legitimate target, as oil revenues are a major source of funding for Moscow’s ongoing war.

The Ukrainian General Staff also reported a separate strike on an RSP-6M2 radar system near Krasnosilske in temporarily occupied Crimea.

The system, used to regulate aircraft movements and assist landings in poor visibility, was reportedly targeted to reduce Russian offensive capabilities.

Ukraine has previously attacked Russian oil refineries and tankers throughout 2024 and 2025, and in recent weeks, the campaign has expanded to include maritime targets in the Black Sea, Caspian Sea, and Mediterranean.
